Water gauge construction



Nov. 18, 1941. J. KACENA WATER GAUGE CONSTRUCTION Filed Jan. 15, 1940 Patented Nov. 18, 1941 WATER GAUGE CONSTRUCTION John Kacena, Chicago, Ill., assignor to Crane 00., Chicago, 111., a corporation of Illinois Application January 13, 1940, Serial No. 313,679

1 Claim.

My invention relates to that type of a water gauge assembly in which the latter is normally supplied with a glass column and is combined integrally with the section of a boiler or the like so as to thereby minimize the hazard of breaking or damaging the glass which danger is commonly present in previous designs available.

Another object of my invention lies in the provision of a construction in which the alignment of the water glass column is constantly maintained and therefore the danger of breaking the glass column during the course of assembling the unit is thus eliminated.

Another important object of my invention lies in the provision of a construction in which the accessibility and simplicity thereof facilitates the convenient assembly of the water glass column to the boiler section and also permits of an access or inspection plug to be installed in axial alignment with the water glass column for ready replacement thereof when required.

A further object lies in the provision of a construction in which the access plug, with relation to its balance of the assembly, makes it very simple to clean the water glass column without removing the glass column itself from the assembly.

Other objects and advantages will become readily apparent upon proceeding with the following description in connection with the patent drawing, in which Fig. 1 is a fragmentary exterior view of a boiler section assembly fitted with a construction exemplifying my invention.

Fig. 2 is an exterior side elevation of the assembly shown in Fig. 1.

Fig. 3 is a fragmentary sectional view taken 7 on the line 3-3 of Fig. 2.

' formed as to permit of upper and lower projecting portions 3 and 4 respectively, with integral connections, as at 5 and 6, communicating with the interior or steam chamber 1 of a boiler section. The said projecting portions 3 and 4 are preferably tapped, as at 8 and 9 respectively, to allow for the insertion of the threaded bushings H and IL. The latter member function as journaling means for the water glass column l3 and also serve to compress packing rings l5 and M for the prevention of leakage therepast. In order to permit of the convenient insertion of the glass column, an access or inspection plug I6 threadedly attached as at l! is provided which is in communication with the boiler section chamber 6. The conventional try-cocks for determining the boiler water levels conveniently are positioned as indicated at 18 and I9 and are also in communication with the interior of the boiler section. Thus it will be apparent that by this construction the projecting portions 3 and 4, preferably integral with the corner of the boiler section, serve to protect the boiler water gauge glass against breakage by forming the containing recess 2, as more clearly shown in Figs. 1 and 3.

Obviously, other equivalent constructions in addition to that shown and described will become readily apparent to those skilled in the art, as for example, the positioning of the protective recess 2 may vary from either a front or rear corner installation to a side installation. Therefore, the measure of the patent protection must be considered in light of the following claim:

I claim: I

In a water gauge assembly, the combination of a boiler section or the like, spaced-apart upper and lower projecting integral portions upon an upper corner of the said boiler section and communicating with th interior thereof, the said projecting portions substantially marking the upper and lower limits of the said water gauge assembly, the upper projecting portion extending above the highest normal water level within the said section, a removable plug mounted upon the uppermost surface of the said upper projecting portion, a gauge glass positioned between the said projecting portions, th said projecting portions forming a suitable recess integrally upon an upper corner portion of the said boiler section to receive the said gauge glass.
